Enhanced photocatalytic performance of Ag3PO4 by simutaneous loading of Ag nanoparticles and Fe(III) cocatalyst

- The photocatalytic activity of Ag3PO4 is improved by the loading of Ag and Fe(III).
- Ag nanoparticles cause an obviously enhanced visible-light absorption of Ag3PO4.
- Fe(III) cocatalyst works as an effective active site for the oxygen reduction.
- A synergistic effect of Ag nanoparticles and Fe(III) cocatalyst was proposed.
